How do I export my game to MAC?

I'm having problem with my MAC builds. I am able to export the game, but the MAC build cannot be executed. I do not have access to a MAC, but people who downloaded the build say the game doesn't run.

I'm aware of the existence of this tutorial: scirra.com/tutorials/1276/exporting-desktop-apps-with-node-webkit

And this thread:https://www.construct.net/en/forum/construct-2/how-do-i-18/how-do-i-create-a-construct-2-91575

But everything still sounds confusing to me. Can anyone help me by making an step by step guide for exporting to MACs and make the builds work?

I may be wrong but i think the issue is that windows and mac handle the file permissions differently, so you need to build the mac version on a mac.

Visit this thread, I think there is something about this.
